Title: Improvements in means for supporting and releasing weft carriers in automatic weft replenishing looms
IPC: D03D45/20
Filed: 1923-04-05
Abstract: 216,990. Hollingworth, E. April 5, 1923. Weft-replenishing mechanism. -- The weft carrier is supported, when in transfer position in a stationary magazine, by a fixed guide and a yielding member engaging the front side of the butt and tip respectively and by a yielding buttengaging member and movable support spaced from the tip of the weft carrier on the rear side of the carrier. The yielding devices on the rear side of the weft carrier may be mounted to move in unison or they may be independent of one another. As shown in Figs. 1 and 2, the weft carrier W is supported on its front side by a fixed guide 17 and yielding tip support 19 and on its rear side by a yielding butt-engaging member 18 pivoted on the lower part of the magazine and a movable support 20 engaging the middle of the carrier and adjustably mounted on an arm 21 pivoted at 22 to the top of the magazine. The holder 16 for the weft ends may be placed rearwardly of the weft carrier in transfer position. In a modification, the yielding members engaging the rear side of the weft carrier are each mounted on a spring-oontrolled arm pivoted on one of the lower tie-rods 12 of the magazine, means being described for operating the arm after a transfer has been completed or evoked. In another form, the yielding butt-engaging member and the movable support corresponding to the support 20 are adjustably mounted on an arm pivoted at the top of the magazine, the upper portion of the arm being off-set so that it may be pivoted on the outer side of the frame of the magazine and not interfere with the placing of the weft carriers in the magazine.

Title: Cigarette making machine
IPC: A24C5/18
Filed: 1962-03-12
Abstract: 987,267. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. March 12, 1962 [March 14, 1961], No. 9434/62. Heading A2C. A uniform cigarette rod is made by continuously feeding to a moving surface quantity of tobacco less than actually needed to make a uniform layer of tobacco of desired thickness for a cigarette rod, compacting the tobacco against the moving surface, detecting the quantity of tobacco in the compacted layer of tobacco and controlling the quantity of tobacco to be added thereto according to the detecting operation for providing a uniform layer of tobacco. As shown tobacco is blown from a conveyer 10 on to the underside of a perforated endless conveyer 21 and held thereon by suction. After passing on the conveyer around a roller 17, the thickness of the tobacco layer is detected by a device 37 which, through a controller 38, controls the speed of a motor 32. The motor is connected to a carded feed drum 31 which receives a second stream of tobacco from conveyers 24, 25 and hopper 23. The tobacco on the drum 31 is picked off by a picker roller 34, rotating at a constant speed, and thrown on to the conveyer 21 through a shoot 30 to make up a rod of the required thickness, the amount of tobacco delivered through the shoot 30 depending upon the speed of rotation of the drum 31. In an alternative arrangement (Fig. 4, not shown) the conveyer 21 may be replaced by a perforated drum. Specifications 933,691, 958,236 and U.S.A. Specification 2,283,394 are referred to.

Abstract: 641,166. Moulding fuel blocks. VLOEBERGHS, A. April 12, 1947, No. 9779. Convention date, Jan. 23, 1941. [Class 87 (ii)] [Also in Group XII] A fuel briquette process consists in heating a mixture of fine bituminous and non-bituminous coals to a temperature below its softening temperature and below that necessary to drive off the volatiles, compressing the preheated mixture in moulds and heating it whilst maintaining the pressure thereon so as to soften the whole of the bitumen therein and thereby cause the bitumen to act as a binder on cooling. In one form, Fig. 1, the apparatus consists of a mould 1 into which is placed the preheated coal mixture, a cover 3 being pressed on to the mould which is then heated, the initial pressure on the cover being maintained. After the whole mass 2 has reached the softening temperature of the bituminous coal and excess volatile matter has been driven off, the cover is removed and a hard, water-resistant briquette extracted from the mould. A multiple mould, Fig. 4, may be used, the base 12 of one mould acting as a cover for the mould beneath it, pressure being applied to the top plate; openings 13 are provided to allow circulation of hot gases around the moulds. Alternatively, Fig. 6, the moulds may be mounted on an endless chain which passes successively under a loading hopper 19, a press 22, which presses on the covers 21 which interlock with the moulds, and through a furnace 18. The covers are automatically removed at the furnace outlet to allow release of the finished briquettes. Specifications 1188/14, [Class 87 (ii)], and 225,849, [Class 50], are referred to.

Patent HK-104695-A (HK)
Title: Method for determining the dew point of a moist gas and apparatus for carrying out the method
Inventor: MUTTER ARTHUR
IPC: G01N25/68
Filed: 1995-06-29
Abstract: A novel method is proposed for determining the dew point of a gas by means of a light ray reflected at a dew-point mirror (3). For measurements of fairly low dew points, in particular at temperatures of -50 DEG C to -95 DEG C, the dew-point mirror (3) is first exposed for a short time to a gas having a high water content. This achieves the result that an initial, fairly thick dew layer which appreciably shortens the measurement time is built up on the dew-point mirror (3). To carry out this method, a dew-point measuring system is proposed which has a gas valve (24), an injector pump (25) and a moistening unit (26) in a secondary circuit (23). A hygroscopic polyamide hose which ensures maintenance-free moistening of the gas by water molecules diffused into it has proved particularly advantageous. <IMAGE>
